NEWTON M. ANDERSON, OF WORTHING'ION, INDIANA, ASSIGNOR OF ONE-HALF TO WILLIAM T. JEAN, OF WORTHINGTON, INDIANA.

'VULGANIZEB.

To all whom it may concern:

Be it known that I, NEWTON M. Armen- SON, a citizen of the United States, residing at Worthin n, in the county of Greene and State 0 Indiana, have invented a new and useful Vuleanizer, of which the following is a specification.

The device formin the subject matter of this application is a apted to be employed for vuleanizing rubber by steam heat, and ordinarily is used in connection with vehicle tire casings and tubes.

One ob ect of the present inventlon is to provide novel means whereby from a single boiler, a circuit of steam through all of the molds is provided.

Another object of the invention is to provide a series of molds so constructed that the tire which is being vulcanized will not be creased.

Another object of the invention is' to provide novel means whereby the tire or other object which is being vulcanized, is made to conform to the molds, without the use of ads, air tubes and the like.

nother object of the invention is to improve the construction of the boiler whereby steam is supplied.

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the present invention ap ertains.

With the above an other objectsin view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein" disclosed can be made within the scope of what is claimed, without de arting from the spirit of the invention.

ject which is being vulcanized conform to the'mold.

In carrying out the present invention there is provided a supporting structure embodying legs 1 carrying a top frame 2. Disposed upon opposite sides of the top frame 1 are molds 3 and 4 of different sizes, in order to accommodate tires or casings of different dimensions. Each of the molds 3 and 4 embodies a saddle 5 curved both longitudinally and transversely so as to receive a portion of a tire or like object. Each of the molds 3 and 4 is equipped with an internal steam chamber 6. Disposed upon one side of the top frame 2 is a heat ing table! rovided with a steam chamber 8. Dis ose opposite to the heating tab e 7 is a ead mo (1 9 embodying a wall 0 curved to conform to the transverse curvature of a tire, the wall 10 bein recessed as shown at 11, to receive the bea of the tire. The head mold 9 ordinaril stands vertically, whereas the other mol s 7, 4 and 3 are horizontally disposed. The bead mold 9 is rovlided with an internal steam chamer 2.

Disposed within the contour of the top frame 2 is a cross 14. From the cross 14 a steam pipe 15 extends to the mold 3, a steam pipe 16 connecting the cross with the mold 4, the mold 9 being connected to the cross by means of a pipe 17 and a pipe 18 forming a connection between the cross and the heating table 7. The mold 9 may be provided with a safet valve 19 and a pressure gage 20 may e interposed in the pi e 18.

isposed below the top frame 2 and within the. contour of the supportin tructure is an upright boiler 21 connected y a pipe 22 with the cross 14. A plurality of heat conducting pins 23 are mounted in the side wall of the boiler 21, the pins 23 rojecting beond theinner face of the si e wall of the boiler, and projecting outwardly beyond the outer side face of the boiler, as clearly indicated in Fig. 3. By means of radial brackets 24, the boiler 21 is connected with a tubular casing 25 spaced peripherally of the boiler and provided with a top 26 through which the pipe 22 passes. The boiler 21 is connected with a water gage 27 located exteriorly of the casing 25. From the boiler 21, a pipe 28 leads to the heating table 7, a pipe 29' connecting the boiler with the mold 9, a pipe 30 connecting the mold 4 with the 21, the conducting pins 23 aidin r materially boiler, the mold 3 being connected with the in raising the temperature 0 the water boiler in a similar manner. within t e boiler. The' steam enerated Disposed alongside of the supporting frame within the boiler passes by way of the pipe and preferably secured as siown at 32 to 22, the cross 14 and the pipes 15, 18, 16 and the legs 1 is a fuel tank 31, adapted to eon- 17 through the several molds.
